I have a problem with some of my screen images distorting. The best way to describe it is with screenshots I think so I have attached 2 images - the first is the image itself with no distortion. The second is a screenshot of how this image appears in my game. The bottom right hand side is slightly distorted. I have tried running the game on different screens with different resolutions and have tried changing the resolution that the exe is compiled at, and have tried different settings for SET DISPLAY MODE - but it always distorts. Any Ideas - please?

You image needs to be sized to the power of 2 (32x32, 64x64 etc). It's something to do with the way DirectX handles images (treats them like textures). Try splitting your image into more than one piece.

So do I have to just use square images?

Well, yes, but not just any size square images. The image size needs to be to the power of 2. 32x32 pixels or 128x128 pixels are just two examples.

Think of how games consoles moved from 8-bit to 16-bit then 32, 64, 128 and (soon) 256-bits and you might understand the maths a little better.

Just noticed it. And I needed it explaining to me before so it was only fair that I pass the info on.

Brilliant! I just extended my images at the bottom to make them 1024x1024 and voila - no distortion. Thanks again Mr P.

If you want pixel perfect images and are only using loaded images for 2d stuff, like menus, you can use ANY size image. You simply use the optional texture flag on the LOAD IMAGE command, ie. add a ,1 on the end. This stops DBPro stretching loaded images.

Boo!

Oh god - that's a bit embaressing. It even says as much in the online help. Thanks a lot Spooky and feel free to berate me repeatedly with chants of "next time RTFM!"

It happens. The manual and help files aren't always clear.

@spooky

Thank you! Like Queeg I hadn't realised the purpose of the texture flag (I suppose I could have tried it ... but hadn't) and was wondering why simple backcloth images had bits missing. Now I know what to do.

@Mr Pointless

Agreed!
